IMPROVEMENT IN FLOUR-BOLTS.

Specification forming part of Letters Patent No. 64,625, dated May 14,1867.

To all whom it may concern: 7

Be it known that I, BENJAMIN BOORMAN, of Waukesha, in the county ofVVaukesha and State of Wisconsin, have invented a new and ImprovedRevolvingFlour-Bolt andIdo hereby declare that the following is-a full,clear, and exact description thereof, which will enable others skilledin the art to make and use the same, reference being had to theaccompanying drawings, forming part of this specification, in which--Figure -l is a transverse vertical section of my invention, taken in theline .10 a, Fig. 2; Fig. 2, a longitudinal vertical section of the same,taken in the line 3 y, Fig. 1.

Similar letters of reference indicate like parts. r

This invention consists in constructing the reel in such a manner thatit willhavea smooth interior, without any obstructions or projections tointerfere with a proper passage of the chop through the bolt. Thisresult is effected by securing the bolting-cloth to the sides of theslats, so as to be even with inner surfaces of the longitudinal slats ofthe reel-frame, as hereinafter fully shown and described.

A represents the box or case in which the bolt is fitted, and B is theshaft of the reelframe, slightly inclined, as usual, from a horizontalposition. G are arms attached radially to the shaft B, and D are slatssecured on the ends of the arms 0, parallel with each other and theshaft B. E represents the boltingcloth, which is secured to the slats Din such a manner as to flush with their inner surfaces. This is effectedby having the cloth E cut into strips a a trifle wider than the spacesbetween the slats, so that the edges of the strips at each side may beplaced against the sides of the slats, and secured thereto by strips b,nailed or screwed to the slats at each side, as shown clearly in Fig. 1.

bran and coarser portions.

The ordinary bolts have the boltin g cloth attached to the outersurfaces of the slats, the latter consequently projecting within thebolt,

and serving, during the rotation of the bolt,

to carry the chop upward, so that it will drop from the top of the bolt,and cause, unless the cloth be very fine, the fine specked portions ofthe chop to pass through, which gives the flour a specked appearance.

By my improvement this contingency is avoided, the flour in the chop isallowed to pass or slide through the bolting-cloth, and the flourseparated from the bran and coarser portions in a perfect manner, andthe bolting process is also greatly expedited, as coarser cloth may beused, and the bolt will not require to be as long as those in presentuse.

Having thus described my invention, Iclaim as new and desire to secureby Letters Patent- .The strips a of the bolting-cloth F, secured to theparallel arms D of the revolving flour; bolt A by means of the strips b,in such a manner that the said strips a shall be flush with the innersurfaces of the said slats D, as herein set forth for the purposespecified.

The above specification of my invention signed by me this 24th day ofMarch, 1866. BENJAMIN BOORMAN.
